In this study, we examined the fidelity of online cognitive–behavioral experiments conducted with Japanese crowd workers. Four cognitive tasks (flanker task, mental rotation task, levels-of-processing task, and mood induction task involving the recall of autobiographical memories) were performed by Japanese crowd workers in a web-based setting and by students in a lab-based setting. We found that all task-specific effects were replicated, except mood induction did not affect perceived social support in both crowd workers and students. The present results validate the fidelity of conducting online experiments with Japanese crowd workers.
